摘要
根据稳恒电流产生磁场的毕奥-萨伐尔定律,利用矢量分析的方法对直角坐标系下的载流直导线在原点处磁感应强度进行了推导,得到了通用解析式。应用这个解析式对抛物线电流、椭圆电流以及双曲线电流在原点的磁场进行了讨论。
The analytic formulation was derivated from rectangular coordinates for Current-carrying Wire＇s origin magnetic induction intensity by using vector analysis on the basis of Biot-Savart Law that steady current produces magnetic field.The magnetic induction intensity at the origin of the parabolic curve electric-current,elliptic curve electric-current and hyperbolic curve electric-current is discussed by the analytic formulation.
